Premade environments/worlds for blender

Hi,
I am wondering if there’s a place to get premade environments/worlds for blender, in the same way there are premade worlds for source filmmaker?

Why do you come and post in the Game Engine Section if its for a source filmmaker?

And No there is no place where you can get Premade worlds ,blender provides each and every individual with the necessary tools required to make such worlds. If its for a Game your talking about i don’t know man it looks like you’ll have to find out yourself bro !!!
“Do more research on google bro” !!!

There is a plugin not free like $3 that allows you to use map data from this site including most to almost all buildings and shapes.

what kind of worlds ???

i make planet maps, asteroids and moons .
Mostly real bodies but also exoplanets and random things

I probably didn’t word my question very well, I was asking if there was a way to import premade worlds into blender the same was you can import them from source engine games into SFM?

There are some on Blend Swap. The architecture, landscapes, and scenes categories would be a good place to look.
